1. the method processing the signal data derived from the signal of the satellite being received from two or more GNSS, oftenOne GNSS has respective clocking error, and described method includes:

  • From described signal data, satellite is eliminated special by the poor operation of the list between receiver user and reference receiver dataFixed clocking error;

    After the elimination of clocking error specific to described satellite, state vector the wave filter defined is applied to byEliminating the signal data set with estimation carrier ambiguities of the specific clocking error of satellite, wherein, described state vector includes;

    First clocking error state, it represents the clocking error of a GNSS;

    And second clock error state, it represents described theDifference between clocking error and the clocking error of the 2nd GNSS of one GNSS.
